I have no idea which forum I should post this in, but this one seems to fit it the best. I saw an "instrument" used by Joseph Wooten at a recent Wooten show I went to. No this is probably going to sound like a really lame description, but it's the best I can come up with. He was using this thing that basically looked like an antenna, and we would move his hand around it, causing some pretty cool electronic sounds to be produced. Does anyone have any idea what I'm talking about, and if so, what the heck is it? I don't know why, but I want one!
